A trainee attending the course on ‘Arc & Gas Welder’ fuses metal parts together using oxygen acetylene flame. The trainee joins metal parts together using gas brazing. The trainee also fuses metals using Arc welding.
Perform these above mentioned operations as per instructions given. The correct equipment- raw materials and consumables will be provided and the candidate must know how to use the same in a safe manner following practices that ensure safety for self- others and the work environment and and assess weld quality through visual inspection.
Perform manual oxy-fuel cutting for a range of standard cutting job requirements using oxy-fuel gas. This is for a skilled cutter who can cut carbon steels in the basic positions.
Perform manual TIG (GTAW) welding for a range of standard welding job requirements. This is for a skilled welder who can weld different materials (carbon steel- low alloy steel) in various positions and prepare various joints including corner- fillet and tee. It also involves set-up and preparation of the equipment and materials provided for operations and interpreting the right information from the WPS.
It covers setting- adjustment- validation or verification of mechanical- pneumatic- hydraulic- electrical- electronic- measuring and control instruments using reference standards in accordance with predetermined standard procedures.
It involves carrying out CNC grinding operations in line with safe working practices and approved procedures- to continuously monitor the machining operations and- where necessary- make minor adjustments or seek the help of the setter to make the required adjustments- in order to ensure that the work output is to the required quality and accuracy.
It involves removal of metal from the outer diameter of a rotating cylindrical workpiece. It also involves inspecting the components and continuously monitoring of the machining operations and making minor adjustments in order to ensure that the work output is to the required quality and accuracy.
It involves producing components that combine a number of different features, such as flat faces, parallel faces, faces square to each other, faces at an angle, steps/shoulders, open and enclosed slots, drilled, bored and reamed holes, internal threads, and special forms. It involves continuously monitoring, inspecting the components and meeting production targets.
Produce the component program using manual data input or by use of a remote computer- saving the prepared program on the machine controller from the computer. This involves understanding the CNC machine tools used in the process- their application and programming- editing and proving process- in adequate depth to provide a sound basis for carrying out the activities.
It involves setting up the CNC turning machine- its work holding devices- tooling- loading the machine operating programmes- conducting trial runs and correcting faults- in order to ensure that the work output is produced as per specification.
It involves setting up cutting tools and workholding devices for producing components that combine a number of different features- conducting trial runs- proving the program tool by tool in single block mode- performing the necessary checks before allowing the machine to operate in full program run mode and then handing over for production.
A trainee attending the course on ‘CO2 welder’ shall be able to read fabrication drawing, examine, clean and clamp parts to be welded. The trainee shall be able to connect work piece with earth cable, welding machine with suitable gas cylinder, regulator, flow meter, and pre-heater when CO2 is used as shielding gas. The trainee shall be able to select suitable wire electrode, feed it to welding CO2 Welding torch through wire feeder, select contact tip gas nozzle and fit into the CO2 welding torch, preheat joints, start the Constant Voltage CO2 welding machine, set suitable welding voltage & wire feed speed and shielding gas flow, produce arc between work piece and continuously fed wire electrode. The trainee also melts the metal and deposit weld beads on the surface of metals or joins metal pieces such as carbon steels, and low alloy steels to a required quality, minimizing distortion and avoiding weld defects.
It involves understanding the customer’s requirement with respect to the mechanical engineering equipment and establish a design brief, further allocate responsibilities and resources to each activity, and ensure that the complete designing process is completed within agreed deadlines and complying with all relevant regulations, identifying design options, evaluation of design options and their presentation in suitable formats, creating detailed design and models using 2D and 3D softwares for design and obtaining design validations from production and maintenance considerations.
It involves select the appropriate equipment and drawing software to use based on the type and complexity of the drawing functions to be carried out and file management and associated customization of installed software including the use of macros- menus and default settings for various kinds of civil work.
